Specification of Letters Patent.

Application filed March 1, 1906. Serial No. 303,706.

Patented July 14, 1908.

To all whom it may concern:

.Be it known that I, JOHN JVWEHINGER, a citizen of the United States, residing at Worcester, in the county of Worcester and Commonwealth of Massachusetts, have invented a new and useful Improvement in Carding-Machines, of which the following is a specification, accompanied by a drawing representing an end view, shown diagrammatically, of a portion of my improved carding-machine.

My invention relates to an improved carding machine and arrangement of the carding cylinder and workers, by which I largely increase the efficiency of the machine, and it consists in the construction and arrangement of parts as hereinafter described and pointed out in the annexed claims.

Referring to the accompanying drawings 1 is the main cylinder which revolves in the direction of the arrow a, and to which stock is applied at one side and removed from the opposite side in the usual and well known manner.

2 is a main Worker of considerable size which revolves in the direction of the arrow 1) at a much less surface speed than the main cylinder 1 and is in carding contact therewith. As the surface s eed of the main worker is less than that o the main cylinder, stock on the main cylinder is transferred to the main worker 2 and is carried by the main worker 2 in the direction of the arrow 1).

I arrange a series of supplemental workers 3, 4 and 5 around the main worker 2 alternating with a series of strippers or transfer rolls 6, 7, S and 9. The surface speed of the supplemental workers 3, 4 and 5 in the direction of arrow 0 is arranged to be substantially the same as the surface speed of the main cylinder 1, and the surface speed of the strippers 6, 7, 8 and 9 is arranged to be faster than the surface speed, of the main worker 2,'but slower than the surface speed of the main cylinder 1 and the supplemental workers 3, 4 and 5. The main worker 2 is larger than is customary in the usual type of carding machines and I am thus enabled to make the supplemental workers and strippers arranged around the main worker 2 of plractically the usual size in machines of this 0 ass.

The stock is fed to the main cylinder 1 by the customary means, not shown, and is transferred from the main cylinder 1 to the main worker 2 because of its slower surface speed as above described. The stock on the main worker 2 is carried in the direction of the arrow 1) and is stripped from the main worker by the stripper 6 which has a greater surface speed than the main worker 2. The stripper 6 carries the stock in the direction of arrow (1 and it is taken from the stripper 6 by the supplemental worker 3, which has a greater surface speed than the stripper 6. The sup lemental worker 3 carries the stock in the 'rection of arrow 0 and it is taken from the supplemental worker 3 by the main worker 2 in the same manner as the main worker 2 takes the stock from the main cylinder 1, as the surface speed of the supplemental worker 3 is substantially the same as that of the main cylinder 1. The stock is now again upon the main worker'2 and is carried in the direction of the arrow 1) until it is stripped from the main worker 2 by the stripper 7 acting in the same manner as stripper 6. From stripper 7 it is taken by the supplemental worker 4 acting in the same manner as supplemental worker 3 and again delivered upon the main worker 2. This operation is repeated by the stripper 8 and supplemental worker 5 and the stock is finally taken from the main worker 2 by the stripper 9 from which it is taken by the main cylinder 1 having a great-er surface speed than the stripper 9.-

I provide a carding contact between each supp emental worker and the main worker 2 in addition to the carding contact between the main worker 2 and the main cylinder 1. I arrange a series of main workers 2, with their attendant sup lemental workers and strippers, two of w ich are shown in the drawing, around the main cylinder 1, each providing a set of carding surfaces, in which the operation already described is repeated, until the stock is removed from the main cylinder'by the means usual in machines of this class.

In describing the operation of my im- 'roved machine I have stated only the surace speeds of the various cylinders with relation to each other, which depends both upon the diameter of the cylinder and'u on the number of revolutions of each cylin er. As above stated, the surface s eed of the main worker 2 is much slower t an that of the main cylinder 1; the surface speed of the stri pers is faster than that of the main wor er 2, but slower than the main cylinder 1; and the surface speed of the supplemental workers is substantially the same as that of the main cylinder 1 and therefore greater than the surface speed of the strippers.

By my improved machine the stock is carded between the main cylinder 1 and the main worker 2 and is still further carded between each supplemental worker 3, 4 and 5 and the main worker 2. In this way I increase the number of carding contacts through which the stock passes in each machine, by providing carding contacts, not only between the main workers and the main cylinder, but also between each main worker and the supplemental workers arranged around it. Thus I greatly increase the capacity and 'efiiciency of each machine without increasing the number of main workers in contact with the main cylinder. In fact, by means of my improvement I gain an increase in the carding surface of the machine with a less number of main workers than are commonly employed, and a smaller main cylinder so that the height of the machine from the floor may be reduced.

The number of supplemental workers and strippers arranged around each main worker may be increased or diminished without departing from the spirit of my invention, which consists in providing carding surfaces apart from the main cylinder by adding supplemental workers in carding contact with each main worker.

I claim,

1. In a carding machine, the combination with a main cylinder, of a main worker in carding contact with the cylinder, a series of supplemental workers in carding contact with the main worker, and strippers for transferring the stock from the main worker to the supplemental workers and finally from the main worker to the main cylinder.

2. In a carding machine, the combination with a main cylinder, of a main worker in carding engagement with the main cylinder and a series of supplemental workers in carding engagement with said main worker.

3. In a carding machine, the combination with a main cylinder, of a main worker in engagement with the main cylinder, and a series of supplemental workers and strippers arranged around said main worker and independently of said main cylinder.

4. In a carding machine, the combination with a main cylinder, of a main worker in engagement therewith, of a series of supple mental workers and strippers arranged around said main worker and providing a series of successive carding contacts between said main worker and said supplemental workers.

5. In a carding machine, the combination with a main cylinder, of a main. worker in engagement therewith, a series of supplemental workers arranged around said main worker and in engagement therewith, a series of stri pers in engagement with said main wor (er and said supplemental workers, with. the last of said strippers also in engagement With the main cylinder.
